Eat smart, move more, chill out

The goal of being “more healthy” is a good one, but can include an almost endless list dietary, activity, and other behavioral changes. Some people may feel overwhelmed and unsure of where to begin. Furthermore, there is a perception that you have to implement all of the changes simultaneously or follow a complicated diet or exercise program in order to see results.

But it doesn’t need to be this way. My Health & Fitness column in the Aiken Standard this week outlines a few simple guidelines that have the potential to lead to significant improvements in health, fitness, and wellbeing. Not only are these things you can implement right now, but they are scalable, so the more you do, the bigger the benefits.

1. Eat smart.Healthy eating isn’t necessarily about eating less or avoiding certain foods, it’s about making smart choices when you shop, cook, or eat out. Many problems with the typical American diet probably have to do with the fact that we tend to eat heavily processed, calorie-dense foods. The major difference between what we eat now and what most people ate before the current obesity epidemic is the processing our food undergoes.

You can eat smart by focusing on eating real food—fresh and minimally processed plants and animals—instead of the processed and pre-packaged food that is so common in restaurants and in meals we eat at home. That isn’t to say that all processed food is necessarily unhealthy, but it would be wise to shift the balance toward more real food.

This isn’t necessarily new advice…it was featured on the cover of a popular book in 2009, after all. But this message seems to have gotten lost in the chaos of health claims made by manufacturers in advertisements and on food labels.

You can do this right now by having a piece of fresh fruit, some nuts, or vegetables for a snack. Later, you can make most of your food purchases from the perimeter of the grocery store, and less from the aisles in the middle.

2. Move more. Most people spend too much time sitting and not enough time moving. In fact, the amount of time someone sits during the day has nearly as much impact on their health as their exercise habits. So, step one is to sit less.

Next, move more, which means just that—finding ways to be active during the day. This includes simple things like standing rather than sitting when you talk on the phone, taking the stairs instead of the elevator, and getting up off the couch during commercials. It also includes dedicating time every day for structured exercise or other activity like yard work, house work, or taking the dog for a walk. Every little bit helps, but aim for a minimum of 30 minutes per day.

Right now you are probably sitting, so stand up and stretch or move around a little. Later, go for a walk or do something active around your house.

3. Chill Out. With so much emphasis placed on diet and exercise, the health effects of stress are often overlooked. Chronic stress can have serious emotional, psychological, and physiological effects that lead to or exacerbate many health problems. While it is impossible to avoid all stress in life, minimizing stressors and managing the way you respond to stress can have important benefits.

Exercise is one good way to manage your feelings of stress as well as the effects it has on your body. Yoga has long been recommended to help reduce and control stress, but all types of exercise can help. Managing time better, including getting enough sleep, is helpful for many people.

Right now you can close your eyes and take a few deep breaths to relax. Later, spend some time doing something you enjoy.

So, if you are feeling overwhelmed by complicated and confusing health recommendations, keep it simple: eat smart, move more, and chill out!

Just in time–New Year’s resolutions that will actually help you achieve your goals.

There are just a few more hours until you have to get started on your New Year’s resolutions.

There are also a few more hours to make New Year’s resolutions, if you are a procrastinator.

The most common resolutions are changes to improve health, including quitting smoking, losing weight, and starting an exercise program. Many people who make these–and other–resolutions get off to a good start, but most will end up failing to meet their goals.

While there are many reasons why people don’t keep their resolutions, part of the problem might be that these should not be the only New Year’s resolutions you make. Resolutions should be the things you need to do to achieve your goals, not the goal itself. Here is an example:

Losing 20 pounds is a good goal for many people. But what that really means is learning about a healthy way to eat, shopping for and preparing appropriate meals, finding time to exercise each day, and focusing on turning these behaviors into lasting habits. In this example, learning how to shop for and prepare healthy meals would make an excellent resolution that would lead toward the goal of losing 20 pounds.

The idea of making resolutions that are steps in the process leading toward a goal instead of the goal itself is the topic of my Health & Fitness column in the Aiken Standard this week. Here are a few resolutions that can help you achieve your health improvement goals, whatever they may be:

Be realistic
Many people fail to keep their New Year’s resolutions simply because they don’t set realistic goals or aren’t realistic about what it will take to meet those goals. For example, running a marathon is an ambitious goal for almost everyone, especially someone who doesn’t exercise at all. It is possible that someone could get in shape to run a marathon, but it will take a long time. A resolution to work up to jogging five days per week, with a goal of completing a 10 k run is more realistic and achievable.

Focus on learning
Making most health behavior changes involve learning as much as doing. Something as simple as eating a healthier meals requires learning about the nutrients that make some foods healthier than others, learning to read food labels to select healthy foods, and learning how to cook and prepare healthy meals. If your resolution is to learn about healthy meals you will be able to achieve that goal and be well on your way to eating a healthier diet.

Manage your time
Most health improvement projects require taking time to learn about, implement, and maintain those healthy behaviors. A major reason the people fail to really get started with or sustain a weight loss or exercise program is time. If you resolve to manage your time to include exercise or meal preparation in your daily schedule you will be much more likely to meet your goals. Trying to add these new activities as “extras” to your already busy day will inevitably lead to them getting squeezed out.

Plan ahead
Most people already know that changing health behaviors can be challenging, even under the best circumstances. It’s no wonder that holidays, travel, and other life events can complicate or even derail an otherwise successful diet or exercise program. Make it your resolution to think about what you can do before, during, and after these (and other) disruptions to your routine to keep yourself on track. Planning ahead and thinking “what if” can make the difference between giving up and catching up on your diet or exercise program after a vacation.

Have a happy and healthy New Year!

Santa’s fitness report, just in time for Christmas.

Right now Santa is making the final preparations for his big night, from checking his list of good boys and girls to packing the toys in the sleigh and giving the reindeer a pep talk. As we can only imagine, a trip around the world in one night is quite a physical feat, so, like an athlete preparing for the Olympics, Santa has certainly been training all year for this  event.

Of course, Santa keeps his training regimen a secret. In my Health & Fitness column in the Aiken Standard this week I make an educated guess as what he does to prepare in the “offseason” and how this training helps him maintain good health despite his less-than-athletic physique. Santa’s training likely includes a combination of endurance, strength, and flexibility exercises.

Endurance training, probably a combination of both high-intensity interval training and long-duration, lower intensity training, leads to a high maximal aerobic capacity and fatigue resistance. Proof for this is the fact that he flies away from each home with a hearty “ho, ho, ho.” If he were out of shape, he would be too short of breath to speak, much less give such a robust farewell!

Resistance training gives him the strength to repeatedly carry his heavy sack of gifts  up and down chimneys. In addition to traditional weight lifting, Santa probably also engages in plyometric training, which involves explosive movements that develop muscle power.

Stretching and exercises like yoga promote good flexibility so he can squeeze through narrow spaces and move quickly without pulling a muscle.

Santa certainly knows that proper training is only part of the answer, so he certainly focuses on sports nutrition, too. Many athletes use specialized sports drinks and foods that provide fluid, carbohydrates, and protein during long events. Santa relies on the cookies and milk you leave for him to provide the nutrients his muscles need to delay fatigue.

We can also learn an important health lesson from Santa. Even though he is overweight, through regular exercise, Santa has reduced his risk of health problems and maintained his fitness at a level that allows him to complete his necessary activities. Like Santa, all of us can benefit from being physically active, whether we are overweight or not.

Happy holidays!

The Health & Fitness holiday gift guide.

If you haven’t finished your holiday shopping yet, you are not alone. As of last week, the average shopper still has half of their gift buying left to do. The good news is that there is still time to pick out perfect gifts for your friends and family, including gifts that will help them meet their health and fitness New Year’s resolutions.

There are many good gifts that can help people get started on their exercise or weight loss programs. Gift guides including gadgets, apps, clothing, and other gear, like this one from Greatist.com. Many of these tools would no doubt be useful for getting people motivated, providing feedback, and even some healthy competition through social networking.

But these are not the things that people really need to begin and be successful making diet and activity changes. After all, no one ever quit an exercise program or failed at losing weight because they didn’t have the right nutrition app or the latest activity tracker. The real reason people struggle is because of factors like time and support from family and friends in the real, not virtual, world.

In my Health & Fitness column this week in the Aiken Standard  I provide a practical gift guide. These are the things you can give your friends or family members to really help them make their healthy lifestyle changes:

1. Time. The most common reason that people quit an exercise program or struggle with weight loss is because of time. That includes time to exercise, obviously. But it also includes time to plan, shop for, and prepare healthy meals and snacks. This year, give the gift of time. Commit to helping your friend or family member plan time to focus on their program and dedicate yourself to taking on some responsibilities to help them do that.

2. Help. In addition to helping find time, you should commit to actually doing things to facilitate your friend or family member’s health improvement program. Taking on chores and projects around the house, picking up the kids after school, and helping with shopping and cooking are examples of things you can do.

3. Support. Anyone who makes a major lifestyle change needs the support of others to be successful. Your role can be to provide encouragement, ask about progress, and take your friend’s program into account when planning meals and other activities together. You should also be ready to provide a gentle (or not-so-gentle) nudge when you see them getting off track.

4. A buddy. People who take on an exercise program with others are more likely to stick with it and be successful. So get involved with your friend or family member. Going for a walk together during a break at work or developing a healthy eating plan as a family is an excellent way to play along. Chances are, these healthy changes will benefit you, too.

So, if you really want to help someone in your life make lasting healthy changes, use the remaining shopping days to come up with a plan. Leave the stress of shopping to everyone else!

From awareness to action: Steps to prevent breast cancer.

This is the last week of Breast Cancer Awareness Month. Through national and local education efforts we should be aware of the impact that breast cancer has on women and their families as well as steps to diagnose and treat this serious condition. We may also have contributed to events from bake sales to road races to support programs that aim to enhance research and treatment for women (and a few men, too) who are dealing with breast cancer.

Now that the pink ribbons are coming down and the NFL players are taking off their pink socks, it is time to focus on something that didn’t get as much attention over the past month: the prevention of breast cancer. This  is the topic of my Health & Fitness column in the Aiken Standard this week.

It turns out that there is a lot that women, especially young women, can do to prevent breast cancer. The good news is that these steps, including not smoking, eating a healthy diet, and getting regular exercise, can also reduce the risk of many other types of cancer as well as other serious health problems such as diabetes and heart disease.

The even better news is that these health behaviors can reduce the risk of breast cancer even in women who have a strong family history or other genetic predictors. Furthermore, these lifestyle factors, especially regular exercise, can help women better tolerate treatment and reduce the chance for cancer recurrence.

Unfortunately, breast cancer prevention doesn’t seem to get the same attention as diagnosis and treatment. In fact, a listing of topics on the National Breast Cancer Foundation Breast Cancer Awareness Month web page includes Early Detection, Diagnosis, Stages, Types, Treatment, but not prevention! This isn’t to say that detection and treatment aren’t important, but preventing breast cancer—something that would benefit ALL women—should be part of the conversation.

Is exercise safe? Yes!

Recently someone asked me why I recommend that people exercise considering that exercise is  dangerous and can lead to injury or death (they didn’t say it exactly that way, though). I responded that while it is true that exercise could be dangerous, it almost always isn’t and serious complications exceptionally rare. Furthermore, regular exercise actually reduces the risk of heart attack or sudden death and screening prior to starting an exercise program can reduce this risk further.

Then, someone asked me about the “CrossFit syndrome” they saw on the news. At first I had no idea what they were talking about, but in our conversation I figured out that it referred to exertional rhabdomyolysis. This form of severe muscle damage can, rarely, result from extreme exercise and, apparently, this has happened  in people doing CrossFit.

But it could result from any overexertion, not just CrossFit and not just exercise. The risk of injury like this can be reduced by starting at a low intensity, progressing gradually, and taking advice from qualified, certified trainers and coaches. Some common sense helps, too: Exercise may cause some muscle soreness, but it shouldn’t hurt.

So, I figured I should write about exercise safety, which I did in my Health & Fitness column in the Aiken Standard this week.

Why BMI matters–Commentary from my soapbox.

My Health & Fitness column in the Aiken Standard this week is about body mass index (BMI), the most commonly used measure of body fatness and health. It was prompted by a recent article in the journal Science that raised familiar questions about whether or not BMI is a valid indicator of obesity and health.

This lead to reports in the popular media about BMI, like this one in Time magazine, the tone of which suggests that doctors and researchers who use BMI don’t know what they are doing. Since I use BMI in research and in practice, I  felt I should address both the article and share some other important points and additional thoughts about BMI.

1. BMI is so widely used because it is simple to measure – it only requires knowing height and weight – and because it is a good indicator of body weight and health risks. That said, it’s not perfect (see below). You can calculate your BMI here.

2. One of the biggest criticisms of BMI is that it can’t distinguish between fat and non-fat tissue, meaning that a person could have a high BMI but not be overly fat. The elevated BMI could be due to excess muscle, as is common in athletes. This is true: BMI doesn’t differentiate between muscle and fat. In fact, it isn’t even a measure of body fat. But in most cases, people who have a high BMI do have a high percent fat.

Don’t believe me? Then try what I call he Wal-Mart test. Go to Wal-Mart someday and measure the BMI and percent fat of everyone who comes through the door. What you will no doubt find is that the majority of the people who have a high BMI are overfat and relatively few have a high BMI due to excess muscle. This is why BMI works so well on a population level.

3. Even though BMI may misclassify some people as overfat when they aren’t, there is a simple way to avoid this: measure their waist circumference. People who have a high BMI due to excess muscle will have a narrow waist (think body builders) and those who are overfat will have a high waist circumference (think Homer Simpson). The point is that it is easy not to misclassify someone if they are in front of you.

4. Another criticism is that it is possible to have a normal BMI but have a high percent fat. This is something that we have seen in our lab and it almost always occurs in people who are thin but unfit–they don’t exercise.  The problem is that a normal BMI indicates good health, but if a person has a lot of fat they really aren’t very healthy.

This is also a valid criticism. And it is especially true if the excess fat is visceral fat, which is stored deep in the abdomen and is associated with higher risks of diabetes, hypertension, and heart disease. But there are other indicators of health risk beyond body fatness, including blood pressure, blood glucose, and blood cholesterol. BMI should be used in conjunction with these other factors to assess overall health.

5. Research also suggests that being overweight or obese according to BMI isn’t necessarily unhealthy and that having a normal BMI isn’t always better. But that is only part of the story. The part that gets left out is physical fitness. It’s true…research shows that the risk of death is lower among people who are overweight or obese but have a high level of physical fitness compared to normal weight individuals who are unfit.

This suggests that regular exercise (to become and stay fit) is at least as important as body weight in determining the risk of death. No question this is true!

However, this doesn’t mean that people who are “fit and fat” are necessarily healthier. The research shows a lower risk of death during a specific follow-up period, but doesn’t make claims about the health during that time. It is possible, even likely, that obesity is associated with some impairment of health—back pain, for example—that normal weight subjects might not experience. Exercise can reduce those problems, but there are likely still some reasons why losing some weight might benefit even those obese individuals who are fit.

Furthermore, I wonder how many obese people are fit enough to have a lower risk of death. I suspect that number is low. Maybe we should add a fitness test to the Wal-Mart test to find out.

6. These problems aren’t a failing of BMI itself, it is the fact that BMI isn’t meant to be used alone. BMI is just one measure of health. When used in combination with others, like waist circumference and physical fitness, BMI is a much better predictor of current and future health problems.

Using BMI alone and complaining that it doesn’t accurately assess health is inappropriate.  Your doctor wouldn’t measure just your blood pressure, find hat it is normal, and proclaim you healthy, right? The same is true for BMI.

With that said, I will step off my soapbox. At least for now.

Good advice for college students. And everyone else.

This came to my attention recently. It’s an infographic about how college students can stay active, get fit, and avoid the dreaded “Freshman 15.”

This is good advice for the rest of us, too. Replace dorm room with living room and cafeteria with kitchen and you have a simple and effective way to improve your health.

The Best Regimen for College Fitness

[The Best Regimen for College Fitness via The Best Colleges]

By the way, studies of weight gain during college show that it isn’t really the Freshman 15. Research shows it’s more like the Freshman 4.6. But that doesn’t have the same impact, does it?

Go for a swim!

It’s summer and it’s hot, so it seems like a good time to write about the health and fitness benefits of swimming. Which is exactly what I did in my Health & Fitness column in the Aiken Standard this week.

Swimming is a great way to get in shape, build muscle, and to help you lose (and maintain) weight. Lap swimming is is about as aerobically demanding and burns as many calories as land-based exercise such as walking or jogging. (Obviously, it depends on the stroke you use and how fast you swim).

Since water is more dense than air, aquatic exercise is lower impact that exercise on land. This means that water aerobics, aqua walking or jogging, and resistance training using foam “weights” or webbed gloves can be done by people with conditions such as arthritis or for injury rehabilitation.

Even swimming leisurely or playing in a pool or lake can burn a substantial number of calories, so it is a healthy way to beat the sumer heat.

If you are interested in using your pool for exercise, you can find information about aquatic exercise in general here and links to suggested exercises here. You can learn more about aquatic exercise specifically for arthritis and fibromyalgia, too.

 

Go for a walk when you fly. Ideas for staying active when you travel.

I typically don’t travel much, but I have been on several trips in the past month or so. Since I’m a bit of an activity geek, I have been noticing the opportunities for and barriers to activity that are present when traveling by air. For the most part, flying involves a lot of sitting—on the plane and in the airport waiting for flights. But it doesn’t need to be this way.

Staying active when you travel is the topic of my Health & Fitness column in the Aiken Standard this week. Of course, I’m not the only one who tries to move more when I fly, both on the plane and in the airport. For example, this guy takes being active between flights to a whole new level. (Yes, he is my hero.)

While it is possible to use your time in the airport to be active, it isn’t always the first thing you think of. Even though nearly everyone does some walking in the airport, moving walkways and trains are an easy alternative to walking the sometimes long distances between terminals. Some airports are better than others at encouraging active transportation in the airport.

For example, the Hartsfield-Jackson airport in Atlanta has a train that runs between the terminals. Right next to the train is a walkway that also connects the terminals. There are signs that tell you how far you have to go (it’s a little less than 1/4 mile between terminals) and art, history, and local information displays line the walkway. Other airports do this too, and some have elaborate light and music shows to keep you entertained. Others have dedicated spaces for exercise, like the yoga room in the San Francisco airport.

Not every airport has made this level of effort to help travelers be more active, but this should change in the future. The American College of Sports Medicine has a Healthy Air Travel task force that aims to develop more opportunities for activity in airports by providing information and other resources to airport management and travelers.

You should also try to be active during your flight, too. Getting up out of your seat (when allowed, of course) or doing simple foot and leg exercises is a good idea. This is recommended to reduce the risk of blood clots that could develop during prolonged sitting. Even though the risk of these blood clots, commonly called “economy class syndrome,” may be low, moving around during a flight is still a good idea.

Between limiting prolonged sitting during the flight and walking more in the airport, my guess is that some people probably get more activity on days when they fly!

Of course, there is another whole aspect of healthy travel that I haven’t addressed: making smart decisions about what to eat for meals and snacks. But that is a story for another time…
